The Biblical Antiquity Of Man

Samuel,Lucas  著
2025/07/30 出版

The Biblical Antiquity of Man, by Samuel Lucas, explores the intersection of biblical accounts and early scientific understanding regarding the age of humanity and the earth. Lucas delves into the scriptural narratives, primarily from the Old Testament, to examine the timelines and genealogies presented therein. He contrasts these biblical chronologies with emerging scientific theories and paleontological findings of his time, grappling with the challenges and potential reconciliations between religious faith and scientific inquiry.This work offers valuable insights into the historical debates surrounding creation, the flood narrative, and the origins of civilization, providing a glimpse into the intellectual landscape of the 19th century, when traditional religious beliefs were increasingly confronted by scientific discoveries. Lucas's analysis serves as a historical document, reflecting the ongoing dialogue between theology and science and the persistent human quest to understand our place in the cosmos.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Gradients and Non-Adiabatic Derivative Coupling Terms for Spin-Orbit Wavefunctions

2025/07/30 出版

Analytic gradients of electronic eigenvalues require one calculation per nuclear geometry, compared to 3n calculations for finite difference methods, where n is the number of nuclei. Analytic non-adiabatic derivative coupling terms, which are calculated in a similar fashion, are used to remove non-diagonal contributions to the kinetic energy operator, leading to more accurate nuclear dynamics calculations than those that employ the Born-Oppenheimer approximation and assume off-diagonal contributions are zero. The current methods and underpinnings for calculating both of these quantities for MRCI-SD wavefunctions in COLUMBUS are reviewed. Before this work, these methods were not available for wavefunctions of a relativistic MRCI-SD Hamiltonian. A formalism for calculating the density matrices, analytic gradients, and analytic derivative coupling terms for those wavefunctions is presented. The results of a sample calculation using a Stuttgart basis for K He are presented.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Exploring the Evolution of Our Ancestors

CRC Press 出版
2025/07/30 出版

This is a captivating evolutionary narrative of the human body, exploring the pivotal traits that make humans unique as a species. It provides a better understanding of why we look the way we do, through an evolutionary morphological lens, by delving into the functional explanations for the unique characteristics of us and our ancestors and the evolutionary pathways that shaped them. It integrates changes in anatomy with functional shifts, but also with underlying genetic and environmental transformations that drove our evolution. The main body of the book focuses around four fundamental themes that have evolutionarily sculpted us into who we are today, ever since the shared origin with the chimpanzee: diet, brain, locomotion and skin. This book not only promises to enrich our understanding of human evolution but also challenges us to reconsider what it means to be human in light of our ancient lineage and ongoing evolutionary journey. It also: Provides a complete overview of the major events of human evolution; Helps readers understand why our body has been shaped the way it is; Integrates genes, anatomy, function, behavior and ecology, creating a more complete picture, written in an accessible text while incorporating many facts and figures building upon both historic and recent literature; Offers an up-to-date view of how anthropologists currently see our evolution; Focuses on four fundamental changes in the brain, diet, skin and locomotion; Explains some aspects of what humans are experiencing today (e.g., why some people are lactose intolerant).

Multifunctional Coatings on Medical Devices

Mdpi AG 出版
2025/07/30 出版

This Special Issue is dedicated to highlighting important advancements in the development of multifunctional coatings on the surface of biomaterials used in medical devices, such as implants, scaffolds for tissue engineering, etc. It is generally acknowledged that one of the most pressing current challenges is the development of biomaterials with new characteristics and properties that can be used in various medical applications. Medical devices are extremely useful in medicine for both diagnostic and therapeutic purposes, and have come to be widely used in plastic and reconstructive surgery, dentistry, orthopedics, neurosurgery, cardiovascular surgery, urology, etc. Multifunctional coatings can endow implantable systems with particular properties and promote their interaction with adjacent cells and tissue fluids, depending on the function and location of the medical device. Furthermore, the surfaces of medical devices can be coated with antibiotic-containing layers with the capacity to counteract bacterial adhesion. Currently, an interesting research direction concerns the development of smart coatings based on biomaterials, which change their properties in response to environmental stimuli. The immobilization of biofunctional molecules and biomolecules on biomaterials to form biofunctional coatings is another challenge that researchers are striving to overcome. Of course, many other remarkable examples could be given. The articles in this Reprint provide valuable contributions to the field of intelligent and beneficial coatings fabricated with and applied to biomaterials, and demonstrate their applications in medicine.

The Biblical Antiquity Of Man

Samuel,Lucas  著
2025/07/28 出版

The Biblical Antiquity of Man, by Samuel Lucas, explores the intersection of biblical accounts and early scientific understanding regarding the age of humanity and the earth. Lucas delves into the scriptural narratives, primarily from the Old Testament, to examine the timelines and genealogies presented therein. He contrasts these biblical chronologies with emerging scientific theories and paleontological findings of his time, grappling with the challenges and potential reconciliations between religious faith and scientific inquiry.This work offers valuable insights into the historical debates surrounding creation, the flood narrative, and the origins of civilization, providing a glimpse into the intellectual landscape of the 19th century, when traditional religious beliefs were increasingly confronted by scientific discoveries. Lucas's analysis serves as a historical document, reflecting the ongoing dialogue between theology and science and the persistent human quest to understand our place in the cosmos.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
